1.Introduction to Mail Server
Installing ASUSTOR’s Mail Server can allow your ASUSTOR NAS to become Mail Server that supports SMTP, IMAP and POP3 protocols and is able to send and receive Email. You can centralize management of accounts, backup emails, provide personalized settings such as automatic forwarding and automatic responses. Additionally, you can also use software such as Thunderbird or Outlook to send, receive and manage your mail.
2.Configuring Your NAS
2.1Signing up for an email domain name
STEP 1
-In the example below we sign up for a dedicated domain name with no-ip.com and then add a hostname (asustorwoody.ddns.net).

STEP 2
-Enter the domain name that you have signed up for into the MX Record field as shown in the graphic below. After entering your domain name, click on[Update Host].
Note 1: You must sign up for a domain name or be using DDNS service in order for Mail Server to send and receive email.
